How can I check if a value is in a multidimensional array?
like I have
?php
$i=0;
while($idt = mssql_fetch_row($query_result))
{
//echo $idt[0]."br";
$produtos_sem_tracking[$i]['cod']=$idt[0];
$produtos_sem_tracking[$i]['idt']=$idt[1];
recusrion is your friend.
?php
$test[0][0] = 'a';
$test[0][1] = 'b';
$test[0][2] = 'c';
$test[1][0] = 'd';
$test[1][1] = 'e';
$test[1][2] = 'f';
$test[2][0] = 'g';
$test[2][1] = 'h';
$test[2][2] = 'i';
function in_multi_array($needle, $haystack)
{
foreach($haystack as $pos = $val)
2 matches
